Specification of Letters Patent.

Application filed January 2'7, 1905. Serial No. 242,940.

invented newv and useful Improvements in Stackers, of which thefollowing isa specification.

. My invention relates to a stacker, and has 1 for its object certainnovel features of construction whereby the efficiency of the machine isincreased, as will be fully described hereinafter.

A further object is to providea stacker whichshall be simple inconstruction, so that the attendance of only one person is required tosuccessfully operate the same.

To this end the invention consists in an arrangement and combination ofparts hereinafter described and claimed, reference being had to theaccompanying drawings, in which Figure 1 is a side elevation of thestacker, and Fig. 2 a plan view thereof. Fig. 3 is a Fig.4 is atransverse section on the line 4 4 of Fig. 2.

Referring specifically to the drawings, the

frame of the machine comprises side bars 6,

. connected by cross-bars 7. The machine is mounted on. wheels, thefront wheels being indicated at 8 and the rear wheels at 9. The

latter are the steering-wheels, and they can links 10 connected with arotatable steeringpost 11, provided with an outwardly-projecting wing12, which the operator straddles to steer the machine. The front wheelsare loose on an axle 13. Clutches 14 are provided to couple said wheelsto-the axle, for a purpose to be hereinafter described. The clutches areoperated by a hand-lever 15 atthe rear end of themachine, where theoperator stands, the

connection between the clutches and the operatinglever being rods 16 andbell-eranks 17, ful'crumed on one of the cross-bars 7. Any othersuitable connection can be used. The draft-animals are hitched to therear end of the machine, the whiflletrees and poles being secured to .adraft-beam 18, extending across the rear end of the machine.

At eachside of the frame is'a pair of uprights 19 and 20, which areconnected at the s top by a transverse rod 21, on which the forkarms 22and a pair of levers 23 are pivotally supported. The fork-arms at theirouter ends are pivotally connected, as at 24, with the fork, whichcomprises the usual spaced parallel bars rear end the fork has a pair ofupright bars 26, which are connected at their top ends to the top endsof the levers 23 by connectingbars 27. Through this connection the forkwill be tilted'when the levers 23 are rocked.

The means forrocking the levers 23 cornprise ropes or cables 28,fastenedto the lower ends thereof, as at 29, and which ropes pass aroundpulleys 30, carried by the uprights 19, and around a shaft 31, journaledin the up-, rights 20. The shaft 31 has a sprocket-wheel 32, which isgeared by achain 33 to a sprocketwheel 34 on a short shaft 35, journaledin standards 36. At its outer end the shaft 35 has a crank 37 forrotating it, and when-this is done the levers will be tilted forwardlyor rearwardly, according to the direction in which the shaft rotates.When the levers are tilted rearwardly, as shown by dotted lines in Fig.3, the teeth of the fork will be lifted, in which position the load iscarried. When the levers are tilted in the opposite direction, the teethdrop down and discharge the load.

The fork is raised and lowered by pushbars 38, which are pivotallyconnected at their outerends to a transverse rod 39, extending betweenthe fork-arms22. The opposite ends of the push-bars are connected by atransverse rod 40, which extends outwardly be- Patented Sept.26, 1905.

yond said bars and forms an axlefor rollers 1 41, which travel on theside bars 6. When the fork is in its lowered position, the pushbars lieon the frame in a horizontal position, as shown in Fig. 3 and by dottedlines in Fig. 1, the rear ends thereof being supported thereon by therollers 41 engaging the side bars 6. When the push-bars are movedforwardly, their outer ends rise and elevate the forkarms'22, as shownin Fig. 1. The rollers travel on the side bars 6, and by inclining thelatter, as shown, the push-bars are readily started. Near the front endof the side bars 6, on top thereof, are placed beams 42, which inclinein an opposite direction to the side bars and on which the rollers alsotravel.

By inclining these beams as shown the pushwound on the drums, thepush-bars are drawn already described.

forwardly and elevate the fork, as already described, and when thecables are unwound the push-bars return, whereby the fork is lowered.

1n the operation of the machine the fork is lowered, as shown in Fig. 3and by dotted lines in Fig. 1. The driver stands astride the wing 12,which guides the steering-wheels. The clutches are thrown to free theaxle 13 from the wheels 8. The machine is then driven to the windrowsand the hay or other material gathered up in the usual manner. \Vhen thefork is loaded, the crank 37 is turned to tilt the fork, as shown bydotted lines in Fig. 3, so that the load clears the ground. The machineis then driven to the stack, and when within a short distance thereofthe clutches are thrown to couple the axle 13 to the wheels 8. Uponcontinuing to drive the machine toward the stack cables 13 are wound onthe drums 44, whereby the pushbars are drawn forwardly and the forkelevated, as When the fork has been elevated sufficiently, the crank 37is turned to push the levers 23 forwardly, which tilts the fork anddumps the load. The machine is then backed from the stack, which unwindsthe cables from the drums and permits the push-bars to drop down slowly,whereby the fork is lowered to the ground. The clutches are then thrownto disengage the axle, and the machine is ready for another load. Onlyone attendant is necessary to operate the machine, as the clutch-lever,steering means, and

fork-tilting device are within easy reach. The machine therefore resultsin a considerable saving of labor, and it effectively serves the purposefor which it is intended.

Having thus described my invention, what is claimed as new, and desiredto be secured by Letters Patent, is-

1. A stacker comprising a supportingframe, fork-arms pivoted thereto, atoothed frame pivoted to the arms, levers pivoted to thesupporting-frame, connections between said levers and the toothed frame,a windingshaft and a pulley, cables lfilSSlDg' over said shaft andpulley, and fastened to the lovers, and means for rotating the shaftwhereby the levers are swung and the toothed frametilted.

2. A stacker comprising a supportingframe, fork-arms pivoted thereto,means for raising and lowering thearms, a toothed frame pivoted to thearms, levers pivoted to thesnpporting-frame, connections between saidlevers and the toothed frame, a winding-shaft and a pulley, cablespassing over said shaft and pulley, and fastened to the levers, andmeans for rotating the shaft whereby the levers are swung and thetoothed frame tilted.

In testimony whereof l have signed my name to this specification in thepresence of two snbscribing witnesses.
